I am using AX 2009.
There is a problem on a specific environment, when doing search a specific string in whole aot, when searching strings
(I dont know if it is the searched string problem, because it is like vendtable.insert()- with a dot inside).
The search ends too fast (couple of seconds), and the result of search is empty (even I know for sure that the search string exists).
That's not enough information to reproduce your problem. Searching for vendtable.insert() works without problems, but the dot means "any character", so vendTableXinsert(), for instance, will be found as well.
Is it possible that the selection was changed to a specific object only?
When you first select the classes node and search for a keyword, all classes are within the search. When you click a class e.g. AssetCopy the field "look in" will be changed when you activate the search form again. Then only this object will be crawled.
